    Forced cooling of permanent magnet DC motors

    "You may consider using a higher voltage and optimize your propellors for the higher speed that will result from the higher applied voltage." Several reasons why I don't want to do that, mostly because of time and cost: 1. Unfortunately in this application propellers get the best efficiencies...

    Forced cooling of permanent magnet DC motors

    The application is a small boat with two of these motors, so the motors could be on for hours. In most situations the motors might only see 200W, but in some situations, such as a headwind, the motors could see 350W for an extended period of time. I've been told since I posted this that not...

    Forced cooling of permanent magnet DC motors

    I have some sealed servo motors that I would like to operate above their rated amperage. I wish to accomplish this by drilling holes in the endcaps and mounting a fan on the end of the motor. I have a spare motor that I can destroy testing, so I can determine the amperage limits empirically if...
